Until recently I may have been the last person in the civilised world (and certainly in my household) not to possess a smartphone. However I was the proud possessor of a Nokia 3120, a candy bar style silver beauty of a phone.
However there were one or two things that I couldn't do (such as check my email, browse the web, look up a map, take a photo or use any form of social media) and they, combined with the deteriorating screen and battery life, pushed me over the edge.
I miss the old phone, constant (and usually silent) companion for over 8 years. All things pass but nostalgia is forever.
